You know, now that I think about it, the first time I went into an Apple Store, I gave them my credit card, and that's when they asked me if I wanted it e-mailed to me. I said "sure", and since then everytime I give them my credit card they ask me the same question. It must be tied to the credit card. So, if you paid cash they would have never asked you that as they wouldn't have a quick way to tie the info over to you. As you say, you can simply get a free case instead, I have two bumpers and a case. Variety is the spice of life, and we want to have fun with our toys, right?
